Mô tả

Impact

Through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key.

Patches

The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. We recommend rotating the node key after applying the upgrade, which can be done by removing the file <datadir>/geth/nodekey before starting Geth.

Credit

The issue was reported as a public pull request to go-ethereum by @fengjian.

Mô tả của NVD

go-ethereum (Geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.16.9, through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key. The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. Geth maintainers recommend rotating the node key after applying the upgrade, which can be done by removing the file `<datadir>/geth/nodekey` before starting Geth.
